Bozeman, MT 59715
Reference: HAVEN
Application No. TBD
SP Application Narrative
Dear Bozeman Planning Staff:
Merry Christmas! We are happy to submit this SP1 application for the HAVEN Shelter project
located on Lot 3A of the Van Horn Subdivision at the end of Pond Row right-of-way, now
addressed as 132 Pond Row.
Project Goals
Since 1979, HAVEN has worked to provide safe intervention for survivors of domestic violence
and prevent future violence from occurring. HAVEN envisions a community knowledgeable about
domestic abuse, fully engaged and committed to the safety and well-being of its members. HAVEN
is committed to reducing the incidence and minimizing the impact of domestic abuse on families
and communities by providing crisis intervention, on-going support, referrals, and education. Last
year, HAVEN served 1,120 survivors of Domestic and dating violence, sex trafficking and stalking
throughout the Gallatin Valley.
Currently HAVEN provides shelter for survivors in a secret location that isolates individuals and
children from members in their community and support network. This facility does not serve the
full needs of survivors in the manner deserving of members of our community. In keeping with
national best practices, a new model for services and support is needed for
Gallatin County survivors.
2
The new facility will be a disclosed location and combine a multitude of critical services while
providing survivors with opportunities to reconnect with our community. The new shelter will
serve 40 survivors- many more survivors than the current shelter can support. The new home for
HAVEN will be transformative for the organization and survivors of violence in the Bozeman area.
Schedule
The design is anticipated to be completed by end of January 2021 and with construction starting in
the spring of 2021.
Phasing
The site is designed to allow for a future phase of additional housing and support spaces. The site
plan submission includes Building A and Building B intended to be built in the first phase and a
provision for Building C to be built in future phases. Building C is intended to include 6 additional
bedrooms for expanded participant capacity. Phase 1 will include sufficient parking, fire apparatus
access, and utility provisions for the future development. We acknowledge that a Master Site Plan
(MSP) application will be necessary if the construction duration exceeds 2 years, which, in the case
of full build-out of Building C, it is likely to exceed, pending future donations. An MSP application
is forthcoming and will likely be in front of the City Planning Department ~mid-January.
Proposed Uses
HAVEN’s new facility is planned to include about 16,000 square feet of service space organized in
two buildings- an Admin and Co-Service Building with a Private Shelter and the Primary Shelter.
The Admin and Co-Services building will include emergency intake spaces, children’s support
spaces, counseling and advocacy rooms, a community space used for community education
programming, and a visitor’s space with computer lab and library. Staff offices will be on-site to
provide immediate support to survivors needing to reside at the shelter. Law enforcement will have
a satellite office at the new facility to help ensure safety and increase collaboration between HAVEN
staff and officers.
The Shelter will include 9 dwelling unit suites for survivors and their children with shared living,
dining, and kitchen spaces. Staff offices will be on-site to provide immediate support to survivors
needing to reside at the shelter.
Site Improvements
The site improvements will include an access driveway and parking, exterior spaces for the survivors,
including an off-leash pet park and dog kennels, children’s play areas, designated smoking areas, and
outdoor gardens. As requested during community engagement, the site will allow for a future
community garden at the Northernmost point. The design intends to utilize native species, design
for limited (low-impact, retentions strategy) stormwater management and irrigation.

Site Utilities & Surface Water
There is an existing 8-inch PVC sanitary sewer main located in Pond Row that flows into the
existing 8-inch sanitary sewer main in West Babcock Street. The system runs to the south in Pond
Row and ends at SSMH J0574 in the cul-de-sac.
There is an existing water line located in Pond Row. A 6-inch ductile iron pipe runs south in Pond
Row to the end of the existing road, and then upsizes to an 8-inch ductile iron pipe after existing
Fire Hydrant #1336. The 8-inch water line continues in the Pond Row right-of-way and loops into
the existing 6-inch water main located in Ravalli Street.
There is no City of Bozeman storm drain located near the site. An existing stream that runs to the
north out of Bozeman Pond flows along the western property line of the site. Build-out of the
proposed City-standard cul-de-sac will gravity flow to the existing storm drain to the north. Stream
setback requirements have been primarily followed with the minor exception of encroachment by
the Survivor parking area with surrounding security fence: The security fence is proposed to be
placed along the line of the setback so construction activities associated with fencing my disturb the
existing soils but no structures would be within the setback.
Stormwater Strategy
Stormwater facilities proposed for the onsite development include a series of boulder pits & dry
wells for retention and infiltration/treatment of runoff. Hardscape areas will be drained to localized
low points and piped to dry wells that are tied into the existing gravels. All stormwater will be
infiltrated on site as there are no public storm drain facilities near the site. No discharge into the
adjacent stream is proposed in connection with this project.
Traffic Impact Study Waiver
We have provided our detailed trip generation calculations to Taylor Lonsdale, PE. We have
requested a TIS waiver as average weekday trips generated are 152/day. Total peak hour trips were
calculated at 11 in the AM Peak Hour and 16 in the PM Peak Hour.
Landscape & Irrigation Strategy
4
The landscape is designed with 3 planting zones, a grassland in the North, brush in the middle of the
site, and riparian woodland in the South of the site. The intent is to preserve as much of the existing
native grasses on the site as possible to and replace with drought resistant plantings within the
majority area of the site. Ornamental plantings will be utilized in centralized gardens.
Permanent irrigation will be provided for lawns, turf block (Grass Pave 2), and the ornamental
plantings. Temporary irrigation will be provided for establishing trees and new plantings of native
grasses.
Frontage
The buildings do not currently “front” the Pond Row Right‐of‐Way nor do they “front” the park
property. The purpose of the new HAVEN facility is to provide privacy for the domestic violence
survivors who will be living on the campus. Providing a design that follows the Landscape Block
Frontage requirements will push the buildings closer to the property line and effectively reduce
HAVEN’s ability to provide a more enclosed, private facility that helps to create a sense of safety for
the residents.
As reviewed in the INF Submittal, the intent and purpose of the BMC Chapter 38 Unified
Development Code is to “protect the public health, safety and general welfare” and verbal
indications from the City found this aspect of the project to be in compliance with the intent.
5
Requested Variances
Based on the proposed site plan for this project, we will be requesting the following variances below
through the City process outlined in BMC 38.250. A justification for each variance is provided:
1. Constructing within the 50-foot stream setback
a. A small stream that drains from the northern side of Bozeman Pond runs along the
west side of the property. As shown on the Site Plan, the HAVEN development
proposes construction of a fence at the border of the 50-foot stream setback for a
distance of approximately 30’. There are no floodplains associated with this stream
and only a small portion of the parking lot will encroach into the stream setback.
While we believe this is technically not a “variance,” we thought it worth noting.
“Separating” Survivor parking with visitors and more accessible (less secure) areas of
the site is an important part of creating a secure and safe site for the Survivors
(hence the need to separate the parking areas—visitors and staff apart from
Survivors.)
2. Curb walk on the west side of the proposed cul-de-sac at the end of Pond Row
a. Verbal communications with the City indicated that we should place non-standard
curb walk is proposed along the west side of the cul-de-sac located at the end of
Pond Row. Bozeman Pond Creek runs along the west side of the cul-de-sac. In an
attempt to mitigate the impacts of the development on the watercourse, and
considering the verbal direction from City staff to do so, we have proposed
transitioning from a standard boulevard sidewalk to a curb walk along the west side.
The following is a list of relevant City comments and Design Team responses to the
applicable CONR Application review comments (City comments are in black, Sanderson
Stewart comments are in red):
Note: The coordination and construction of Pond Row will take place with this project. Pond Row
must be built out to the western property line. The only available mechanism for not constructing
Pond Row to City of Bozeman standards would be a variance. Landscaped block frontage will be
applied to Pond Row as it is in a residential district.
After discussions with the City, we now propose a cul-de-sac at the end of Pond Row in place of
constructing Pond Row out to the western property line.
1. BMC 38.220.080. - Site plan submittal requirements. The application must meet the SP1
and PLS form requirements. Include a detailed narrative explicitly stating how each
comment is being addressed, including sheet numbers and any other pertinent information.
Please incorporate the following items with your site plan submittal.
a. Block frontage requirements must be met with this project. Include block frontage
annotations.
2. BMC 38.250 – Variance procedures. If the applicant does not wish to construct Pond
Row they may apply for a variance through procedures outlined in this section. The
Owner/Applicant has discussed this with City Staff and a cul-de-sac is now proposed instead
6
of full construction of Pond Row along the frontage of the property. City staff has indicated
their verbal approval/direction of this approach.
3. BMC 38.510.030. - Block frontage standards. The landscaped block frontage standards
must be applied to this project along Pond Row. All buildings must front the Pond Row
right-of-way as space allows and include a public entrance clearly visible and accessible from
the street with parking in the rear or sides of the building. Buildings that cannot front Pond
Row due to inadequate space must front to the park and meet the mixed block frontage
requirements (either storefront of landscaped) per BMC 38.510.030.I. If parking is to be
located at the sides of the buildings it must not exceed 50% of the frontage width. Based on
verbal discussions with City staff, it is now understood that we meet Block frontage
requirements along the short section of the cul-de-sac frontage and because of safety
considerations of Survivors, a sidewalk connection from City sidewalk to the internal
portions of the site is not proposed.
4. BMC 38.520.030.C.5. – Connection to adjacent properties. A pathway connection to the
park adjacent to the property must be provided. A pathway designed by the Landscape
Architect is to be provided as a connection to the Pone Row cul-de-sac sidewalk, which
then, in turn, connects to the existing trail/path system at the existing southwest corner of
Pond Row, providing pedestrian access to the park adjacent to the property.
5. BMC 38.520.040. – Non-motorized circulation and design. All pathways must have a
minimum 5’ unobstructed surface. The pathways are currently shown at 4’. The intent of the
internal paths is for Survivor use, not to provide publicly accessible routes at publicly-
accessible standards.

Applicant Questions
1. Will the City permit the combination of water and sewer connections into one service lateral
(for all 2 [or 3] buildings) given that it is one User/Owner?
Generally, a line serving a single building or facility is considered a service line; and a line serving more than a
building, or intended to serve more than one building or facility is generally designated a water main. Based on the
information provided, engineering, fire, and water & sewer do not have enough information to make a decision on
combining water and sewer connections. For budget purposes, it is still the intent and desire of the
Applicant to provide one water and sewer connection for both buildings. While they are two
separate buildings (and a future potential for a third), there is not foreseeable splitting of the
property resulting in two (or three) separate owners. Fixture counts from the Mechanical Engineer
have been appended to this narrative. The Mechanical Engineer has determined that a 4” sanitary
sewer service would be adequate to service the sewer demand of all three buildings.
2. Will the City allow for part of the Haven driveway to exist in Pond Row right-of-way (as
Pond Row is not fully built out along the frontage of the property with no apparent
intention of full build-out)? We envision a cul-de-sac or appropriate fire truck turnaround
that could be constructed at the end of the existing Pond Row, from which the Haven
driveway access could connect. Not applicable with updated site plan.
7
BMC 38.400.060 Street Improvement Standard - Pond Row road is classified as a “local” street.
Development of the Site requires the improvement of the street along the Site’s frontage to City standards, which
includes proper drainage, dedication of right-of-way (ROW), pavement, detached sidewalks, landscaped and irrigated
boulevard strip, trees within the boulevard, curb and gutter along with proper access points into the site. A cul-de-sac
has now been proposed after conversations with City staff. The only variance requested will be to
provide a curb walk (no boulevard) at the west side of the cul-de-sac to minimize impact to the
existing stream. The cul-de-sac area that encroaches into Haven property will either be dedicated as
a Public Access and Utility Easement or Have will go through the Subdivision Exemption (SE)
process… this is still in discussion with the Owner.
3. Will the City allow for the on-site stormwater system to connect/outfall into the adjacent
stream to the northwest, as long as we mimic/match pre-developed rates and comply with
City drainage standards in the Design Standards & Specifications Policy? (Records for this
existing drainage ditch/stream were not found in our preliminary research of the publicly
available records for the site.) Not applicable with updated site plan.
The applicant must determine the historic drainage pattern associated with the subject property. Based on the
information provided engineering does not have enough information to provide an answer. Typically, with any
development the subject property must satisfy the City’s water quality and water quantity standards (further outlined
below in the stormwater section), no matter the location of the terminus point. The applicant is encouraged to limit
discharge into adjacent water bodies to preserve the health and promote the longevity of the community’s natural
resources. This is not applicable anymore. Our stormwater strategy will store and infiltrate all
stormwater on-site.
Easements
1. Bozeman Municipal Code (BMC) 38.410.060.B.2. Easements - A ten-foot utility
easement (power, gas, communication, etc.) must be provided along the developments
property frontage prior to site plan approval. The applicant may contact the engineering
department to receive a copy of the utility easement contract.
· The application shows a proposed ten foot utility easement along Pond Row Rad.
The applicant needs to provide proof that the utility easement exists prior to site
plan approval. If a utility does not exist, the applicant must file a utility easement
contract prior to site plan approval. According to recorded Plat E-39-C for the Van
Horn Subdivision, a 10-foot utility easement exists along the western property line
that fronts Pond Row. Plat E-39-C is now attached with this submittal for reference
purposes.
Stormwater
1. DSSP Section (A) (4) Water Quality - The applicant must include a drainage plan with
post-construction storm water management controls that are designed to infiltrate,
evapotranspire, and/or capture for reuse the post-construction runoff generated from the
first 0.5 inches of rainfall from a 24-hour storm preceded by 48 hours of no measurable
precipitation. For projects that cannot meet 100% of the runoff reduction requirement, the
remainder of the runoff from the first 0.5 inches of rainfall must be either: a. Treated onsite
using post-construction storm water management control(s) expected to remove 80 percent
total suspended solids (TSS); b. Managed offsite within the same sub-watershed using post-
construction storm water management control(s) that are designed to infiltrate,
8
evapotranspire, and/or capture for reuse; or c. Treated offsite within the same subwatershed
using post-construction storm water management control(s) expected to remove 80 percent
TSS. Noted. A more detailed drainage plan with calculations is attached to this submittal.
2. DSSP Section (C) Water Quantity - The applicant must provide either on-site detention
with release rates limited to predevelopment runoff rates or on-site retention. Retention
ponds must be sized based on a 10-year, 2-hour storm intensity. The proposed stormwater
strategy is to retain and infiltrate runoff, on-site. See the drainage report and calculations as
well as the attached drainage plan.
3. Montana Post-Construction Storm Water BMP Design Guidance Manual Seasonal
High Groundwater - The proposed project is located in an area that is known to have
seasonally high groundwater. Engineering requires that the applicant confirm that
groundwater will not impact the function or maintenance of the proposed facilities. Industry
guidance recommends a three-foot minimum separation from the bottom of the proposed
facility to the underlying groundwater table. Noted. We are in discussions with the Owner
for further groundwater monitoring and understand that some changes to proposed depth
of storm drainage may be necessary if groundwater is found to be higher than the ~6-7’
found in the bore logs of the geotechnical report.
4. DSSP Section II.C.2 - Detention facilities located in areas accessible to the public shall
have a maximum water depth of 1.5 feet and maximum basin depth of 2.5 feet. It appears
that the detention facilities exceed a maximum basin depth of 2.5 feet. Not applicable with
updated site plan.
5. BMC 38.410.080.F – It appears that the proposed detention facilities appear to occupy 50-
percent of the required front setback. Not applicable with updated site plan.
Water Rights
1. BMC 38.410.130 (A) (1) Water rights - The applicant must contact Brian Heaston with the
City Engineering Department to obtain a determination of cash-in-lieu (CIL) of water rights.
Noted. We have reached out to Brian Heaston to begin this coordination effort.
Wastewater & Water
1. DSSP Section (V) (B) Sanitary Sewer System Design Criteria - The applicant must
provide an estimate of the peak-hour sanitary sewer demand certified by a professional
engineer for the proposed project. The City will analyze and determine if sewer capacity is
available to accommodate the project. The calculated sewer demand is 56 GPM per the
calculations attached to this narrative.
2. DSSP Section (V) (A) Main Size - The applicant is advised that the subject property is
located in the northwestern (4975 HGL) pressure zone. Water pressures around the subject
property vary from 80 to 90 psi. The water distribution system must be designed to meet the
maximum day demand plus fire flow and the peak hour demand requirements upon future
development. The applicant is advised that water connections to the subject property will
most likely need to be taken from North Ferguson Ave and not from Durston. All additions
to the water system will be designed and installed in accordance with the Montana
9
Department of Environmental Quality Circular 1; Montana Public Works Standards and
Specifications (MPWSS); City of Bozeman Modifications to MPWSS; and the City’s most
recent Water Facility Plan. Noted. We have provided the proposed size and design of the
water lateral to service fire flows to building B and domestic water to Buildings A & B (with
potential water stub to Building C).
3. BMC 38.410.070 (B) (2) Municipal water, sanitary sewer and storm sewer systems -
The length of service lines from the main to the structure may not exceed 150 feet in length,
unless approved in writing by the city. We hereby request this approval in writing as the
general dimensional constraints of the site and layout warrant water and sewer laterals in
excess of said 150’. The water lateral(s) are approximately 470’ in length and the sewer
lateral is approximately 235’ in length with cleanouts spaced appropriately.
Transportation
1. BMC 38.220.080 (A) 2.g Traffic Generation - The applicant must submit a peak hour
trip generation value to the City to determine whether a traffic impact study is required.
Maximum peak hour trip generation is 16 (for PM Peak Hour). A TIS waiver has been
requested from Taylor Lonsdale, PE at the City Engineering Department.
2. BMC 38.400.060 Street Improvement Standard - Pond Row road is classified as a “local”
street. Development of the Site requires the improvement of the street along the Site’s
frontage to City standards, which includes proper drainage, dedication of right-of-way
(ROW), pavement, detached sidewalks, landscaped and irrigated boulevard strip, trees within
the boulevard, curb and gutter along with proper access points into the site. A cul-de-sac has
now been proposed per City standards after conversations with City staff.
3. BMC 38.400.010.A.5. Dead-end streets and alleys – As presented, the proposed internal
parking area appears to have a number of areas that could lead to a dead-end for emergency
vehicles needing to access the site. The design must comply with City design specifications
and standards along with any City-adopted International Fire Code. No dead-ends longer
than 150 feet are permitted without an approved turn-around. The applicant must provide
an engineering/fire approved turn around for emergency vehicles. (see figure below) The
new proposed site plan should mitigate the concerns presented in this comment. Turning
movements and fire truck access has been discussed with Scott Mueller at the Fire
Department.
4. BMC 38.540.020 (M) Stall, aisle and driveway design - Snow removal storage areas must
be sufficient to store snow accumulation on site. Snow storage located behind parking stalls
in a development that provide only the minimum required parking will not be considered
sufficient. Noted, snow storage areas have been annotated and shown in Civil drawings.
5. BMC 38.400.080 (A) Sidewalks - A City sidewalk must be constructed along the Pond
Row Road frontage upon future development. The minimum width of a sidewalk along a
local street is 5 feet per the DSSP Section IV.B.3. A sidewalk has been provided along the
radius of the proposed cul-de-sac at the end of Pond Row per City standards.
10
6. BMC 38.540.020.J. Parking lot curbing – Off street parking areas must have a perimeter
concrete curb around the entire parking area, including drive access. Perimeter curbing has
been provided around parking areas and drive accesses.
7. BMC 38.520.40 Non-motorized circulation and design - Connections to adjacent
properties (including parks and trails). Provide pathways that connect to adjacent properties.
A path is provided from the proposed buildings to the public right-of-way as well as a
sidewalk around the cul-de-sac that connects to the adjacent trail system and park. Note that
the design intent of this path is to provide access to adjacent parks/trails but not to
encourage public access to within the site.
Transportation
8. BMC 38.410.100 Watercourse Setback – Where a development is cross by or is adjacent to
a watercourse, the developer must mitigate the impacts of the development on the
watercourse.
a. Show the adjacent Bozeman Pond Creek along the developments western edge. The
extents of Bozeman Pond Creek are shown on the provided Civil Sheets where it
impacts the development’s western property line.
Conditions of Approval
1. The applicant must provide and file with the County Clerk and Recorder's office executed
Waivers of Right to Protest Creation of Special Improvement Districts (SID’s) or special
districts for the following, if not already filed:
a. Street improvements to West Babcock Street including lighting, signalization, paving,
curb/gutter, sidewalk, and storm drainage.
b. Street improvements to Fowler Ave including lighting, signalization, paving,
curb/gutter, sidewalk, and storm drainage.
c. Intersection improvements at Ravalli Street and Pond Row Road including lighting,
signalization, paving, curb/gutter, sidewalk, and storm drainage.
d. Intersection improvements at West Babcock Street and Fowler Ave including
lighting, signalization, paving, curb/gutter, sidewalk, and storm drainage.
The document filed must specify that in the event an SID is not utilized for the completion of these
improvements, the developer agrees to participate in an alternate financing method for the
completion of said improvements on a fair share, proportionate basis as determined by square
footage of property, taxable valuation of the property, traffic contribution from the development, or
a combination thereof. The applicant must provide a copy of the filed SID waiver prior to site plan
approval. Noted.

· The drawing shows 3-phase overhead power along the east property line. This is incorrect.
There is a single phase overhead line that runs along the east property line of the properties
on Pond Row. The drawing shows the overhead power line extending past the south
property line. This is incorrect. The single phase power line extends to the dashed property
line east of the Off-Leash Pet Park. Single phase is now proposed.
11
· Will the new building need three phase power? If so the overhead line along the east
property line will need to be rebuilt to bring 3-phase power to the two building locations.
There is three phase underground to the southeast near the Mall which may be a location to
extend 3-phase to the southeast corner of the lot. This will require a NWE engineer to
investigate once an application is submitted. Single phase is now proposed.
· There is a 2” gas stub located at the northwest corner of the lot near the cul-de-sac which
can be used to bring gas to the two buildings. This project now proposes to tie to the
existing 2” gas stub at the location described.
· Site plan needs to show a 10-foot utility easement along the proposed gas route and any
electric primary route. Without knowing the electrical need, 3-phase or 1-phase, the utility
easement will need to be established once this has been determined and which location for
bringing power to the site has been established. A 10-foot utility easement is proposed on
the civil site plan. There is a possibility that Haven will decide to re-plat the property to
dedicate the cul-de-sac ROW in Pond Row. In the event that this happens, this may be the
most appropriate means of dedicating said utility easement.
· Need to show proposed transformer and meter locations. Transformer & meter locations
need to be approved by NWE. Transformer & electric meter location is now proposed at
eastern wall of Building A. Gas meter is located on east wall of Building B.
· If the transformer is going to be installed close to a curb protective bollards will need to be
installed, according to NWE standards, on the curb side of the transformer. Or install the
transformer back away from the edge of the curb about three feet and bollards can be
omitted. Transformer not located next to curb.
· If the buildings will be requiring 3 phase power a transformer pad site should be planned.
Typical 3-phase pad is going to be a 7’x7’ pad and it will need to be a minimum of 10’ from
the building unless the exterior material, near the transformer location of the building meets
fire code for non-combustible material then, the transformer can be placed closer. This will
need to be worked out between the NWE engineer and the applicants engineer or architect.
Transformer & electric meter location is now proposed at eastern wall of Building A.
· Meter locations will need to be approved by NWE. NWE policy is to maintain a minimum
of 3-feet between the front of the meter and landscape screening and allow easy access to
the meters for operation and maintenance. This can be determined through the design
process after an application is submitted through NWE and the area engineer will work
through allowable shrubs and plants for screening and to determine adequate clearances for
access to our meters. Transformer & electric meter location is now proposed at eastern wall
of Building A. Gas meter is located on east wall of Building B. Planting plan illustrates
accessibility to meters/transformer for NWE’s review purposes.
· Plan views and elevation views do not show proposed meter locations. Need to see where
meters are to be located to provide comments per location to windows, doors and other
openings or entry’s. Submitting an application to NWE will get NWE involved and the
NWE engineer can help with this process. Transformer & electric meter location is now
proposed at eastern wall of Building A. Gas meter is located on east wall of Building B.
· In regards to Landscaping, NWE does not allow any large deep rooted trees or bushes
within the utility easement. Noted. Planting Plan is attached with this submittal.
· It is my recommendation that they submit a service application to NWE as soon as possible
to get the process started. This will assure working with the NWE engineer that it gets
started in the right direction. Noted. The Development Team will be starting this process
12
soon.
